They're not even close to comparable. Worrying about privacy and then focusing on Big Tech is like trying to swat away a mosquito while you're being devoured alive by three bears.
A huge amount of government surveillance either depends on Big Tech contractors or explicitly leverages Big Tech's disregard for privacy. For example "geofence warrants" wouldn't be possible if Big Tech wasn't collecting and storing all that location data in the first place.
Let's rein in Big Tech. Now what? Law enforcement and intelligence agencies are going to leave it at that and not seek alternative paths? I do not understand how anyone is more eager to address something that merely facilitates the problem than the actual problem itself.
